What happened in the meantime?

One of the arguments in favor of KJV being the only Bible used is expressed in the personal testimony of Will Kinney.

I began to read several books on the Bible version issue and studied and prayed a lot about it. Over time God began to open my eyes to see that either the King James Bible was the true words of God and all other versions were but poor imitations, or else God did not really mean what He says in the Bible about “Thy word is truth” and “the Scripture cannot be broken”. (John 17:17; 10:35)¹

He gives us two supporting verses. They are quoted here in both the KJV and the NKJV for comparison.

Sanctify them through thy truth: thy word is truth.

John 17:17 KJV

Sanctify them by Your truth. Your word is truth.

John 17:17 NKJV

If he called them gods, unto whom the word of God came, and the scripture cannot be broken;

John 10:35 KJV

If He called them gods, to whom the word of God came (and the Scripture cannot be broken),

John 10:35 NKJV

The presupposition is that the KJV answers both of Jesus’ claims: 1) it is the Truth; and 2) it keeps the Word of God unbroken. If this is true, what about the time between the last words penned in the Bible and the time the KJV was issued?

We can use the current common understanding that John wrote the last words in the Bible², and that he wrote about 95 AD³. We will use the issue date of the KJV’s first printing, 1611. This gives us 1,516 years between the time Revelation was put to parchment and the unbroken truth of God was established⁴.

The question arises: What happened in those 1,516 years to the un-brokenness of the Word of God? How did the original language change from Greek, to Latin, to Middle English? How was the truth preserved all those years and through all those changes in language?

Whatever the answer to these questions, the following question then is to be asked: does the same answer apply for the 403 years after the first publishing of the KJV?⁵
